Цель исследования: анализ литературных источников и сравнительная оценка результатов исследований об эффективности выполнения эластографии почек у практически здоровых пациентов, выработка нормативов жесткости для почек практически здоровых пациентов и разработка стандартной технологии выполнения исследования.

Материал и методы

Материал и методы. Проведен поиск научных статей, публикаций, клинических рекомендаций, отчетов съездов и научных конгрессов в информационно-аналитических системах ELibrary, Google Scholar и PubMed за 2013–2024 гг. по ключевым словам: эластография почек, оценка жесткости почек, ультразвуковая эластография почек, renal elastography, renal stiffness, ultrasound elastography of the kidneys. Также проведен анализ списков литературы найденных статей по соответствующим критериям.

Результаты

Результаты. По соответствующим ключевым словам было подобрано 288 статей, в том числе публикаций научных конгрессов и конференций, 39 из которых были признаны авторами соответствующими тематике научного обзора. Из списков литературы найденных статей было дополнительно выбрано 8 статей. В результате поиска была выделена группа статей, среди которых проанализирован материал для получения ответов на поставленные вопросы.

Заключение

Заключение. Проведенный анализ данных литературы является одним из этапов систематизации ранее проведенных исследований в области эластичности почек и позволяет отметить важность исключения всех описанных предыдущими авторами факторов, вызывающих значительную вариабельность показателей жесткости неизмененной паренхимы почки. В результате обзора авторы показали возможности использования двухмерной ультразвуковой эластографии сдвиговой волной в оценке жесткости паренхимы почек неинвазивным методом и необходимость выработки стандартной методологии исследования, сводящую к минимуму погрешность.

Aim

Aim: analysis of literature sources and comparative evaluation of research results on the effectiveness of performing renal elastography in almost healthy patients, development of stiffness standards for kidneys in practically healthy patients and development of a standard technology for performing the study.

Material and methods

Material and methods. A search was conducted for scientific articles, publications, clinical recommendations, reports of congresses in the information and analytical systems eLibrary, Google Scholar and PubMed for 2013–2024 by keywords: kidney elastography, assessment of kidney stiffness, ultrasound elastography of the kidneys, renal elastography, renal stiffness. The analysis of the literature lists of the found articles according to the relevant criteria was also carried out.

Results

Results. According to the relevant keywords, 288 articles were selected, including publications of scientific congresses and conferences, 39 articles were recognized by the authors as corresponding to the subject of the scientific review. And 8 additional articles were selected from the literature lists of the found articles. As a result of the search, a group of articles was created among which the material was analyzed to get answers to the questions posed.

Conclusion

Conclusion. The analysis of the literature data is one of the stages of systematization of previously conducted studies in the field of renal elasticity and allows us to note the importance of excluding all factors described by previous authors that cause significant variability in the stiffness of unchanged renal parenchyma. As a result of the review, the authors showed the possibility of using 2D shear wave ultrasound elastography in assessing the stiffness of the renal parenchyma by a non-invasive method and the need to develop a standard research methodology that minimizes the error.
